This page serve as a repository to keep my theses and other work that is not formally published.

Master thesis in the University of Tokyo

Basically it is a modified version of my publish work in PRR.
Here is the thesis.

The term paper for my edX Quantum mechanics course, 8.06x [Finished on 14 June 2019]

What Is a Single Photon and How to Detect It?

In this term paper, I want to address a question puzzling me for a long time: why light sometimes behaves like waves and sometimes like particles. This question can be answered in a fairly consistent way (but by no means in an intuitive way) under the quantum framework. Inspired by the first part of Professor Alain Aspect’s quantum optic courses, we answer the above puzzle by exploring the nature of a single Photon. I thank Professor Jim Freericks for suggesting me this interesting topic.

PS: On 14 April 2021, Alain Aspect gives a lecture aimed at general public talking about Wheeler’s delayed-choice experiment. It was a fascinating talk. You can find the videos here.

Master theses on my Engineering training side

Master Thesis (finished in July 2019, in Chinese): Failure Modes Classification and P-M Interaction Hysteretic Model of Reinforced Concrete Columns.

We use techniques from machine learning community to solve the problem of classification of failure modes for reinforced concrete columns in Structure Engineering community. The skewed nature of the database makes the problem little subtler. We also briefly discuss how to consider the effect of changing axis load on the shear and bending capacity of the reinforced concrete columns. I would say both approaches are heuristic, providing possible treatments that I find natural and reasonable concerning these two problems. This thesis was supervised by Professor Xiaodan Ren and Chao-Lie Ning.
